This isn't that hard. Most of the time, the "changes" are useless UI Slop: "we've moved notifications to this TOTALLY BETTER OTHER SPOT IN THE SCREEN that one of our designers snuck a commit in with and nobody wanted to argue about it, because the last time it just came down to differing opinions. Its not really better but it's different!"

And the other reason is because most users probably have day jobs and need to get something done.

GTFO of my face with product tours.

Atlassian is particularly enraging, especially if you're dealing with setting up "new" accounts. I've worked with your shitware for a decade now, I know how it works, DO NOT FORCE ME TO MAKE TEN CLICKS TO GET RID OF A FUCKING INTRO.

Rather, invest your time into a good, logical UI and, most importantly, good AND CURRENT documentation.
